Finally—3 Causes of Hormonal Weight Gain, Explained

Even if you lead an active lifestyle, fill your fridge with fresh fruits and vegetables, and get a solid eight hours of sleep each night, you still might be unexpectedly gaining weight. Why, you ask? According to Carly Brawner, holistic nutritionist, health coach, and founder of Frolic and Flow, a hormone imbalance might be to blame.

"Many people hear the word 'hormone' and think sex, puberty, and periods, but we have sleep hormones, stress hormones, and even temperature-regulating hormones," explains Brawner. Hormones are responsible for sending messages throughout our bodies, and as it turns out, they can have quite a bit to do with fluctuations in weight.

"Hormones are tied to weight gain because they are crucial to metabolism, the nervous system, and reproduction—three bodily systems that are important for maintaining healthy body weight," Brawner tells MyDomaine. In addition to weight gain, there are several other symptoms to look out for if you think you may have a hormone imbalance, including "fatigue, sugar cravings, sleep issues, and mood changes," says Brawner.
